We attempted to synthesize Zn1–xMgxO particles from a mixture of ZnO and MgO or Mg(OH)2 particles using our original particle synthesis method, pulsed laser melting in liquid (PLML), and confirmed that an alloying reaction occurred. The solid solubility x of Mg in ZnO depends on the mixing method of ZnO and MgO or Mg(OH)2 particles. The Zn1–xMgxO particles with solid solubility x = 0.09 and 0.20 were obtained from mixture particles prepared using mechanical mixing and coprecipitation methods. This is due to the smaller Mg(OH)2 particles produced by the coprecipitation method and the higher frequency of contact between ZnO and Mg(OH)2 compared to the mechanical mixing method. The solid solution limit of Mg to Wurtzite-type ZnO in this study was found to be between 0.20 and 0.24, which is comparable to the Mg solid solution limit of x = 0.2 reported for the conventional solid phase reaction of common ceramics.
